Sol- gel theory of amoeboid movement was first given by Hyman, later supported by Pantin (1923) and Mast (1926). According to this theory, amoeboid locomotion is due to change in the viscosity of cytoplasm.
In Whittaker's system of classification prokaryotes belong to the kingdom

Animalia
Fungi
A genophore is made up of
a single double stranded DNA
a single stranded DNA
RNA and histones
histones and non- histones
There exists a close association between the alga and the fungus within a lichen. The fungus
fixes the atmospheric nitrogen for the alga
provides protection, anchorage and absorption for the alga
provides food for the alga
releases oxygen for the alga
